    A Flood Warning is in effect for two areas of central Nebraska — listed in the alert record as Greeley NE and Valley NE — according to the flood warning product issued by the National Weather Service Hastings NE.

    The warning record describes the affected area as "West Central Greeley County in central Nebraska... Southeastern Valley County in central Nebraska..."

    On conditions in those two counties, the record states: "Flooding of area creeks, streams, and other low-lying and flood-prone locations continues, particularly along the Mira Creek in and near North Loup. Although excess water continues to gradually recede, it could take several more hours for the Mira Creek to drop back below its minor flood stage."

    The National Weather Service Hastings NE record directs residents of the warned area to "Be especially cautious at night when it is harder to recognize the dangers of flooding," to "Be aware of your surroundings and do not drive on flooded roads," and to "Please report observed flooding to local emergency services or law enforcement and request they pass this information to the National Weather Service when you can do so safely."

How we work

This site models an investigative reporter rather than a wire desk. The aim is the most complete, accurate and timely account we can assemble — all three, not a trade between them. Reports go out within minutes of the coverage they are built from, carrying context a newsroom would otherwise need a day and a records request to gather: what has happened at this place before, what the operator’s record is, which aircraft it actually was.

Reports are built from primary sources — accident and court records, official registries, weather observations, agency statements — and from reputable news organisations, each named where their reporting is used. Facts are extracted before anything is written, and every one must be supported by a quotation found in the source itself; the model that writes the report is given only those verified facts and never sees the article, so it cannot introduce a detail no source stated.

Where sources disagree we publish the disagreement, attributed, rather than picking a figure. Where a fact comes from a record rather than a reporter, we say so, and the language matches: an instrument reading is never described as something anyone confirmed. Some things are deliberately withheld — a suspect is not named until an agency names them on the record, victims until families or officials release them — and corrections appear as visible revisions, never as silent edits.

None of that makes a report true. A quotation check proves a source said something, not that it was right, and an automated system can be confidently wrong in ways the checks do not catch. If something here is wrong, the feedback above is how it gets found. The full methodology, including what we refuse to publish.
